Figure 11 is a sectional detail taken substantially on the lines llll asshown in Figure '7.

Figure 12 is a'sectional detail on an enlarged scale taken substantiallyon the lines- I2-l2 as shown in Figure 5. Referring to the drawings, theholder generally designated It) includes a head I i and a guard memberl2 secured together by means of a pivotal connection designated l3. 'Amagazine M is receivedwithin a pocket [5 defined by the head II andguard l2, and this magazine carries a flexible-1 ribbon blade 16 ofconsiderable length. One edge of the blade is sharpened as indicated atll. The head ll inclines forwardly at an acute. angle from its verticalneck portion 8 and is secured by means of a suitable connection E8 tothe vertically extending handle I9.

The magazine I4 is generally rectangular in shape and is relatively thincompared to its length and width. The lower edges of the rectangle maybe rounded as indicated in the drawings. The magazine may include a base20 and a cover 2! secured by any convenient means such as, for example,by means of projecting pin elements 22 on the base 20 which extendthrough apertures 23 in the cover2 I and which are later deformed asindicated at 24 to prevent disassembly (see Figure 10).

A horizontalslot 25 provided in the base 29 separates the main portionof the base 29 from thehorizontal bridge 26. A slot 21 in the cover 2|is aligned with the base slot 25, and a forwardly extending flange 28 onthe cover 2| overlies the bridge 26. the upper surface 29 of the bridge26 and under the. flange 28. The ribbon blade It extends from a supply,coil positioned within a recess 3! provided in the base 20. The otherend of the blade l6 may be received in a mounting slot 32 provided in atake-up drum or spool 33 positioned The ribbon blade It extends acrosswithin the recess 34. The recess 34 is also formed in the base 26 and ispositioned symmetrically with the recess 3| with respect to the bridge26.

A noncircular opening 35 is provided in the reel 33, and a cooperatingnoncircular projection 36 on the knob 31 is carried on the head H andprojects through an aperture 38 provided therein. A flange 39 on theknob 31 prevents disassembly with respect to the head Th size of theaperture 38 is somewhat larger than the hub 46. The reel 33 is providedwith outwardly extending hub portions 62 which are received within theaxially aligned openings 63 and 64 provided in the base 26 and cover 2|respectively. It will be recognized that the knob 31 need not beattached to the head I l but may comprise a separate and distinct partif desired, and indeed may be shaped to be received within a convenientrecess provided on the handle l9. Rotation of the knob 31 serves to windthe ribbon blade l6 onto the reel 33 and hence cause the blade to moveacross the bridge 26 and unspool from the reel 36.

Rounded surfaces 42 and 43 are provided on the base 26 and are contactedby the ribbon blade It at each end of the bridge 26. Guide flanges 44and 45 extend along the sides of the curved surfaces 42 and 43respectively, and these guide flanges are positioned adjacent thesharpened edge H of the ribbon blade I6. As shown,

in Figure 4, the guide flanges merge at their lower ends into the endwalls 46 of the base and terminate at their upper ends near theintersections 4 secure additional stiffness. Recesses 65 in the headafford clearance for the annular ridges 53.

Ratchet means are provided to prevent unspooling of the drum 33 andthereby maintain tension on the ribbon blade l6. As shown in thedrawings, this means includes a plurality of ratchet teeth 54 formed onthe side face of the reel 33, together with a pawl element 55 forengaging the teeth 54. This pawl element 55 may be formed as an integralpart of the cover 2| and may be separated by a stamping operation fromthe remainder of the cover'along the radial line 56 and intersectingcircumferential line 51. The pawl 55 is deformed inwardly as shown inFigure 12, and its integral connection with the cover 2| providessuflicient resilience to permit the pawl to deflect outwardly and allowthe ratchet teeth 54 to pass by in one direction. Reverse rotation ofthe reel 33 is prevented.

From this description it will be observed that a of the curved surfaces42 and 43 with the upper plane surface 29 of the bridge 26. Thesharpened edge ll of the blade is kept away from contact with theflanges 44 and 45 in order to maintain the blade at its maximumsharpness and to avoid the possibility of dulling before use.

Means are provided for maintaining the heel edge 41 against the innersurface 48 of the cover 2|, and as shown in the drawings, this means includes the slanting of the surfaces of the curved ends 42 and 43 so thatthe heel end 41 of the blade l6 travels over a shorter arc than theportion of the blade adjacent the sharpened edge H, as is clearly shownin Figure 11. Thus, tensioning of the ribbon blade l6 between thesubstantially conically curved portions 42 and 43 causes the blade tomove toward the low side and thereby move the heel 41 against thesurface 48.

As a further aid in positioning the sharpened edge so that it will notbe contacted prior to use during shaving, and in this way to insure itsmaximum sharpness, the recess 3| is provided with a tapering wall 49which is larger on the diameter adjacent the cover 2| than on the innerdiameter at the bottom of the recess. The angle of inclination of thewall 49 and the inclination of the curved surface 42 have each beenexaggerated in Figures 9 and 11 of the drawings for clarity ofillustration. The effect of this tapered bore is to cause the individualloops of the coil to expand to the largest diameter and hence move theheel edge 41 of the continuous ribbon blade l6 into contact with thecover 2|. The sharpened edge 11 is in this way held out of contact withthe bottom 50 of the recess 3|. An annular nonmetallic washer 5| may bemounted in the bottom of the recess 3| if desired as a furtherprotection for the sharpened edge H, and this washer 5| may have acentral aperture to receive the centering boss 52 (see Figure 7). Thecover may comprise a metal stamping, if desired, and T be provided witha pair of annular ridges 53 to ratchet and pawl device has been providedfor preventing a reverse rotation of the reel 33, which device requiresno separate or additional parts and which may be manufacturedeconomically on a quantity basis.

The tendency of the coil loops to expand within the recess 3|, togetherwith the friction of the'blade I6 over the curved surface 42, providessufiicient frictional resistance to maintain proper tension on the bladeas it reaches the bridge 26. The ratchet device 54, 55 preventsunwinding of the blade at the other end of the bridge.

Theribbon blade l6 extends from the coil 30 through a slot 58 leadingfrom the recess 3| to the curved surface 42, the outer end of the slotbeing defined by the upper edge 59 of the end wall 46. A similar slot 66is provided on the other side of the base communicating with the recess34. Nonmetallic sealing elements 6| may be provided adjacentthe slots 58and 60 in a position to contact the ribbon blade l6. These sealingelements 6| assist in excluding entrance of water or foreign matter intothe recesses 3| and 34.

Means are provided for maintaining the pivoted guard member in closedposition and for urging the magazine |4 into engagement under the lip 66provided on the head I As shown in the drawings, this means includes acam member 61 pivotally mounted with respect to the handle l9 and head Hby means of the pin 68. The nose 69 of the cam is adapted to abut thelower end 76 of the guard |2. A slot"|| in the head loosely receives thetab 9 so that the guard may have limited universal swiveling movementand may also move longitudinally in a direction par allel to the headThe shelf 12 on the guard |2 supports the magazine l4 along its loweredge so that upward movement of the guard |2 serves to clamp themagazine |4 between the lip 66 and shelf 12. Since the cover or guard |2is free to swivel with respect to the head H, the magazine M is alignedby the lip 66 and not by the shelf 12. This clamping action servestohold the magazine |4 securely in place and further acts to provideadditional stiffness for the flange 28 which overlies the ribbon blade|6. Under this clamping force the flange 28 deflects slightly so thatthe ribbon blade |6 is held tightly on the bridge seat 29. The upperedge of the guard I2 is provided with the usual comb teeth 13. As

shown clearly in Figures 9 and 10, the bridge 26 is cut away on itsunder side to provide an entrance opening 14 leading into communicationwith the horizontal aligned'slotsfi, 21 and provided in the base coverZlandhead H- respectively.

The cam 61- may-berotatedto an-inoperative position as shownby thedotted lines in Figure 1 to permit the guard I2 to be swung 'to openposition as indicated by the dotted li'nesin Figure-2; The magazine Mmay'then be installed by placing its lower'edge on theshelf l2 and thenswing"- ing' the guard 52' toward closed'positionsothat' the magazine Mremains in the pocket 15'; As the guard is swung toward" closed positionthe noncircular' projection 36 enters-the noncircular' opening in thetake-up spool orreel 33; The relatively loose fit of the knob member Winthe head" opening 38 facilitates thisoperatiorr;

The flange 28 on the magazine cover 21 underlies the lip 66 on the headH. The cam; GT is swung to its'op'erative position so that the nose: 69engages the lower edge 10 of the guard l2 and moves the guard andmagazine upwardly. to

clamp the magazine between. the lip 66 and shelf '12. The razor isthenready for use.

When the exposed or active portion of the sharpened edge I! becomesdulled throughuse, the knob 37 is rotated to bring, afresh portion intoposition onthe bridge 25. A very large number of active lengths are thusprovided on the relatively long ribbon 16. When the blade [6 has beencompletely used up, that is, wound on the take-up reel 33, the holder I0is opened and the used magazine l4 withdrawn. A new magazine is theninserted into the pocket ['5 and the device is again ready for use. Thenew magazine may be handled without using great care since the cuttingedge I? is well guardedandishielded. against contact, except fortheexposed or active length extending along the bridge 26 between theflanges 44 and 45. If desired, a portion of the blade l6 which isinitially exposed may have its cutting edge l1 dulled to further insureagainst accidental injury when installing the magazine l4 into theholder Ill. The magazine I4 is automatically self-aligned on the razorhead H by reason of its linear contact with the underside of the lip 66and the point contact of the supporting guard i2 and swinging cam 61.When once installed the knob 31 is turned to bring the sharpened portionof the blade into operative position.
